ditto that. I must have half a dozen or more tractors with 711 and 722 loaders, and at least 1 setting behind the barn.
there are 2 models.. one with a 5.5" box, and one with a 3.5: box, measured from a corner at the front where the hole is, to the end of the box at the weld.
that picture is so low res, I can't tell.. but it looks like it may be the small box.
though difficult, you can coax a small box onto a regular mount bracket on an 00/01.. just takes a lil practice. there are also specific brackets to let you mount the small box to an 00/01 series tractor.... as someone pointed out..the bracket set used to mount a 1-arm laoder is usually worth more than the laoder. in the case of a trip style.. that loader is usually valued somewhere between 50-150$ and the brackets, as much.. witht he hip / tranny bracket being the oimportant one.. usually costing 100$ by itself.
there will be a front bracket that can be torched out of 1/2" plate, as well as lower strap brackets to the trans that can be made from 3/8 or 1/2" etc. none of the 3 cyl brackets are compatible with the 4 cyl models... though if you buy the laoder.. DO get the brackets from that machine as you may be able to trade them for the correct brackets.
for a trip loader you can chain down the 3pt lift and run a hose from the top cover accessory plug to the lift cyl and use the 3pt handle to lift it.
or get a diverter valve that makes it so you don't have to chain the 3pt.. just swap between them..
or get a single remote for the top cover ( used about 150$ ) ( new.. figure 400++ ) or get a power beyond plate ( 100$ and a cheap OC valve from a farm store ( 100-150$ ).. etc.
lots of options.. just gonna be a fudge sickle to make it all fit..and no show till you et the brackets anyway..
